The Japanese company will acquire the stake from funds affiliated with AutoStore's majority shareholder Thomas H. Lee (THL) Partners and other investors including EQT Private Equity, valuing the firm at $7.7 billion.
Founded in 1996, AutoStore has 20,000 robots deployed across 35 countries and counts Puma, Best Buy and Siemens among its customers. The company also touts a design method that allows customers to store four times the inventory in the same space in a warehouse.
Such technology enables e-commerce companies to deliver packages faster and more economically, as online shopping has surged during the COVID-19 pandemic.
SoftBank in January last year took part in a $263 million funding round in Berkshire Grey, which develops artificial intelligence-based logistics automation systems used by its customers - Walmart Inc, Target Corp and FedEx Corp - in their warehouses and distribution centers.
